The world’s fastest runner goes from 50 m/s to 140 m/s in 4.7 seconds. How fast is she accelerating?
What is 19.15 meters per second squared (m/s²)
Shaleket builds a simple circuit for her science fair project using a battery, a light bulb, and a resistor. She measures the voltage across the light bulb to be 9 volts, and the total resistance in the circuit is 3 ohms. Jada wants to make the bulb brighter by increasing the current to 5 amps. How much more voltage will she need from her battery to reach this goal?
What is 6 volts?
This element, the most abundant in the universe, is so light that Earth's gravity can’t hold much of it in our atmosphere.
What is hydrogen?
